For those that are interested in such things, the pendant I'm wearing here is a graphic representation of the Fibonacci sequence. It's great for breaking the ice at parties. If you are partying with mathematicians. I also have one with a real dead scorpion in it.

At least, I hope it's dead.

Several people have suggested I do an Amazon wish list so they can send me cool stuff that I want, so I've started one here. There's not much on it right now, but far be it from me to make it harder for people to buy me nice stuff.
